Application filed June 5, 1 916. :SerialNo. 101,779.

To all whom it may concern: 1 1

Be it known that I, IVILLIAM DRUMMOND, a citizen-of the United-States, residing at Manteno, in the county of Kankakee, State of Illinois, have invented certain new and useful Improvements in Adjusting Devices for Harvesting-Machines and the like, of which the following is a specification.

This invention relates to improvements in adjusting devices for harvesting machines and the like. Harvesting machines such as grain binders, headers, corn harvesters, and the like'are adjusted to regulate the height at which the grain is cut by tilting of the frame. This is frequently very laborious and diflicult, particularly when the machine is thrown out of balance by the addition of an engine for driving the cutting and binding mechanism of the harvester as is now a growing practice, or by the weight of a heavy person or by a lighter person than the average which the machines are commonly designed to accommodate.

It is the main object of this invention to provide an improved adjusting mechanism with means counterbalancing such an unbalancing weight thereby rendering the machine easy of adjustment.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a side view showing a grain binder embodying the features of my invention, only such parts of the machine being illustrated as is deemed necessary to illustrate a practical embodiment of my improvements.

Fig. II is a detail perspective view showing structural details of my improvements.

In the drawing similar reference numerals refer to similar parts in both views.

Referringto the drawing, 1 represents the frame of a grain binder and 2 the bull wheel thereof, the grain wheel or the wheel on the grain side is not illustrated. The frame 1 is mounted for tilting adjustment to bring the knives, designated generally by the nuv Specification of Letters Patent.

meral 3,;in proper relation to the ground for cutting the grain at the desired height. The tongue 4 ispivoted at 5 to the forward projecting curved draw bar 6. A seat 7 is provided in the usual position for the operator.

The structure illustrated has an engine 8 mounted on the rear part of the frame, the engine being connected to the driving shaft 9. The adjusting lever 10 is provided with an arm 11 connected by the link 12 to the tongue 4:. The link is preferably provided with a series of holes 13 adapted to take the bolt 1% disposed through the tongue so that the link may be adjusted relative to the tongue.

To counterbalance the weight of the engine 8 or other unbalancing weight I provide a coiled spring 15, the lower end of which is adjustably connected to the tongue by the clip 16 and its upper end being connected to the frame by means of the hook 17, the hook being engaged over one of the uprights 18 of the frame. This hook is preferably provided with a turn-buckle 19 by means of which the spring can be adjusted.

WVith the parts thus arranged an unbalancing weight such as that of the engine 8 or the weight of a heavy man can be counteracted by the spring so that the tilting of the machine is easily eflected.

I have illustrated the adaptation of my improvement to harvesters, corn harvesters, headers and other harvesting machines of this class as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent:

1. The combination in a grain harvester of the class wherein the main frame is mounted for tilting adjustment on a centrally disposed carrying wheel and is provided with an operators seat and an engine on the rear thereof, of a tilting means comprising a tongue pivotally connected to the front of the frame, a lever pivotally mounted on the frame and connected to said tongue by a link, a coiled tension spring, a clip adjustably connecting one end of said spring to said tongue, and a hook connecting the other end of said spring to said frame so that the spring tends to tilt the frame forwardly, said hook being provided with a turn buckle whereby the tensiq n ef pr n y b adigstedof'the dclizss whereirilmithe r A 11 W 7 trally disposed ca gfying 'whee' and is prg inded i n" .mwrw n thereof, "of ati in'g' means comprlsmg a' tongue pivotally connected 110 the fl-eat of the frame, a lever pivotally mounted on the m 1 e by;
